Programmable Control Unit for monitoring the back pressure. This control unit provides the possibility to individually program the pack pressure one would like to drive in. This way, one can reach the maximum performance. The portion of back pressure resulting in a loss in performance is filtered out.
Therefore, this sports exhaust combines all advantages in both the lower and higher range of revolutions (rpm), since the back pressure can be exactly dosed to enable the engine to gain the maximum performance. The programmable control unit features an illuminated display showing all functions in plain text in 3 different languages (German, English ,Italian) and provides 3 basic modes to be operated via a remote control, namely:
a)Cruise mode - the exhaust gas valves open later b)Sports mode - the exhaust gas valves open earlier c)Open mode - the exhaust gas valves remain open In both the cruise mode and sport mode, one can individually program when the exhaust gas valves shall open.
One big advantage is that the control unit recognizes the driver’s operation characteristics. If the driver accelerates aggressively, this is identified by our device by the kind of back pressure that is generated, and the exhaust gas valves open immediately. Usual acceleration results in a later opening of the exhaust gas valves.
